Data classes for storage and service bus, such as Queue, Topic, Subscription, Rule, etc. should have additional constructor parameters with default values. This will allow creation of an instance in one statement. This should be done for the data classes that are instantiated by the user.

Old:
rule = Rule()
rule.filter_type = 'SqlFilter'
rule.filter_expression = 'messagenumber > 3'

New:
rule = Rule(filter_type='SqlFilter', filter_expression='messagenumber>3')

New (alt):
rule = Rule('SqlFilter', 'messagenumber>3')
